STRUCTURAL WORK FOR BUILDINGS.

SPECIFICATION forming part of Letters Patent No. 485,871, dated November 8, 1892.

Application filed July 19l 1892. Serial No. 440,470. (No model.)

To @ZZ whom it n1/ty concer/t:

Be it known that I, JOSEPH M. LARIMER, of Chicago, Illinois, have invented certain new and useful Improvements in Structural Work for Buildings, of which the following is a specification.

My invention has relation to certain improvements in the structural work of buildings, and more particularly to the structural work of buildings whose frames are composed of metal columns and girders.

One feature of my improvement relates to a novel means of reinforcing metal columns, and particularly to a means for reinforcing or strengthening the columns com posed of metal bars having outwardly-presenting flanged heads and centrally-connected webs, such as have been heretofore patented to me and are now known o n the market as Larimer columns. In many cases it is desired, in order to render the column available in peculiar relations, to so construct it that it may beloaded eccentrically-that is to say, columns are frequently placed in such position that the load is carried upon one side only-and in these cases it is desirable to increase the thickness of the metal at the periphery of the column, and this I do by combining with the outwardly-presenting flanged heads of' the metal beams of which the column is composed reinforcingplates, which are preferably flat steel or iron plates and are bolted or riveted Hatwise upon the heads of such columns. By so doing the column may be strengthened at the point where strength is needed without adding to the weight or cost by making it unduly heavy, as would result from putting the same amount of metal into the several heads or sides.

Another feature of my invention relates to a novel method of connecting together two or more of the heads of the beams composing these columns by means of a sectional ring, which is adapted to form a base-ring, a capring, or a bracket; 'but which, as hereinafter described, is applied as a bracket.

A feature of this part of my invention relates to providing the sectional ring with lateral extensions or wings, which are bolted or riveted together and are adapted to support beams or girders carrying a weight in a plane parallel to the side of the column to which said ring is attached.

Another feature of my invention relates to a novel form of connecting-plate which is placed between the ends of the columns where a plurality of them are superposed-as, for example, in the construction of high buildings. The particular form of plate which I employ is of such shape as to connect the several heads of the beams of which the column is composed and at the same time to afford spaces interior of the external diameter of the column for pipes, wires, or other of the accessories of modern metal-frame buildings.

In the accompanying drawings, Figure lis a side elevation of a column of `my construction` and intended particularly to showin side view the reinforcing-plates and showing, also, sectional supporting-rings with gil-ders supported thereby. Fig. 2 is a plan View of a column composed of two bars or beams having their webs bent and connected centrally, the heads of the respective bars being connected together in pairs by sectional connecting-rings or ring-sections. Fig. 3 is a side elevation of a section of a column, showing one of its connecting ring-sections forming a bracket to support two beams, the latter shown in end elevation. Fig. 4 is a plan View of the same, the supported beams being broken away to show the bracket beneath, the outlines of said beams showing in dotted lines. Fig. 5 is a plan view of the beam and with a ring-section connecting three of the heads thereo" and having a lateral extension to form a bracket. Fig. G is a plan View showing a modified construction of the ring-section, and Fig. 7 shows the improved form of plate.

In the drawings the column is shown as composed of two I-beams A A, having their webs bent upon curved lines and their heads presenting outwardly, the beams being connectedat their middles through an interposed fillet or I-beam B by means of the rivets C.

As shown in Figs. 1 and 2, the heads of these I-beams are reinforced by the plates D, which are fiat metal plates riveted to the fianges of the heads of the I-beams, and, as shown, each head is so reinforced. This is sometimes desirable in making a column; but

in many cases where an eccentric load is to be carried less than the whole number of heads may be thus reinforced.

E represents a ringsection adapted to form a bracket to give lateral support to the girder E. This ring-section, as shown in Fig. 2,0011- nects two of the heads of the respective columns, so that the two columns forming the beam are connected not only centrally, but are also connected externally or at their peripheries. These ring-sections are secured over the reinforcing-plates.' ,In the construction shown in Figs. 3,4, and 5 the connecting medium is formed of two metal bars E E2, disposed iatwise with reference to each other and connected together at one end, but separated at the other, and made to embrace the heads of the beams A A, two of said heads being connected as shown in Figs. 3 and 4, while three of said heads are thus connected as shown in Fig. 5. The parts ot' the bars which are thus bolted {iat-.wise together form a lateral extension or bracket F, serving to support a load intermediate the ends of a colum nas, for example, the grders G. (Shown in Figs. 3 and 4.) Thus the double purpose is served of connecting together the heads of the columns and increasing the strength of the latter, while at the same time avery strong supporting-bracket is provided.

In Fig. 6 the same ide-ais exemplified, except that the connecting ot' the heads of the column is emphasized, while the lateral Hang-e may he adapted to rest upon the top of a girder or to support one, as the case may be.

Referring now to Fig. 7, H represents a plate which is placed upon the end of a column to adapt it to receive a superposed column. l

Said plate has its corners cut away, so that in outline it presents substantially the" form of a Greek cross, although of course its form may be varied, the essential feature being that it shall have sufficient width to furnish proper bearing-support for the end of a superposed column, while at the same time providing the spaces h, in which pipes, electric wires, dac., may be run. The chief utility of this form over those now on the market is the fact that byits use considerable economy of material is gained without impairing the utility o r strength of the plate.

Without limiting myself to precise details of construction, I claim- 1. In structural work forbuildings, the com.- bination, with a column composed of metal beams having centrally-connected webs and outwardly-presenting heads, ot' a metal segment or ring-section connecting the heads of the respective beams of the column, substantially as and for the purpose described.

2. ln structural work for buildings, the combination, with columns composed of metal beams having centrally-connected webs and outwardlypresenting heads or flanges, of metal connecting segments or ring-sections composed of hars having two of their ends separated and adapted for connection to the heads of the column-beams and their outer ends connected together and extended laterally to form a supporting-bracket, substantially as described.
